Will this work?

Or rather, the switched hot coming back to the load (light, receptacle, etc.) may not be white.

For the 2011 National Electrical Code, neutral must be taken out to the switch, necessitating, here, a 3 conductor cable. This renders academic the question of which hot conductor gets the white wire. Use red and black (doesn't matter which) for raw hot and switched hot.

The neutral is left curled up inside the switch box for future use.

Yes it will work without neutral at the switch box, given an ordinary toggle switch as opposed to a motion detector or some kinds of dimmers that need neutral to operate.
